CORPORATION OF CALIFORNIA COMBINED COOKER AND COOLER Original application filed April 18 1928,

This invention relates to combined cookers and coolers and more particularly to a manner of drum construction for such a combined cooker and cooler.

15 This application is a division of my oopending application, Serial No. 271,070 filed April 18, 1928, for comb1ned cooker and cooler.

An object of this invention is to provide a structure of treating chamber including a shell which is fluid tight and which is formed at half sections united together at the bottom at a rectangular section by welding the adjacent edges of the half sections together, the section of the shell at which the weld 1s efiected being rectangular in cross section to permit the structure of the shell to yield at its bends or corners to allow an effective and easy weld to be made at the adjacent edges, providing a chamber for the reception of steam or other gas pipes for admitting steam or other fluidinto the chamber.

Other objects and advantages of this invention it is believed will be apparent from the following detailed description of a preferred embodiment thereof as illustrated in the accompanying drawings:

In the drawings:

Figure 1 is a top plan view of the combined cooker and cooler embodying this invention.

Figure 2 is an end sectional elevation thereof taken substantially on the line 22 of Figure 1.

Figure 3 is a sectional end elevation taken substantially on the line 3-3 of Figure 1.

In the preferred embodiment of this invention illustrated in the accompanying drawings, 1 indicates what is commonly known in the art as a cooker or treating chamber into which cans which-have previously been hermetically sealed are introduced to receive what is known as the final cook. The cooker may be operatively connected with a second cooker (not shown) of the same con struction as the cooker 1, or may be directly connected with a cooler 2 as illustrated in Figure 1. The cooker 1 and cooler 2 may be of substantially the same construction, and

Serial No. 271,070. Divided and this application filed January 7,

Serial each includes a shell 3 which is formed in half sections 3 and 3".

The shells 8 are usually of such size that it is impractical to construct the same of a single portion of material and it is required that these shells be fluid tight to retain the heated gas or steam which is admitted to their interior through any suitable means such as the steam pipes l which are mounted in the steam chamber 5 thereof. The cooler 2 is generally provided with no such steam pipes 4, but in some types of coolers it is desired to maintain substantially equal pressure within the shell of the cooler as within the shell of the cooker so that gas under pressure, usually cold, may be admitted through pipes similar to the pipes 4 mounted in a chamber similar to the chamber 5.

In order to unite the half sections 3 and 3 in a simple and efiective manner, and also in order to provide a chamber 5 for the pipes 4, I have found that if the shells are bent longitudinally to form substantially L- shaped sections 6 and 7, having bends 8 where the shell diverges from the cylindrical form, and also having a second substantially rightangled bend 9 where the adjacent edges 10 of the shells meet, that I am enabled to weld these adjacent edges 10 longitudinally of the structure to form a substantially onepiece shell which is fluid tight.

In welding these large structures, I have found that it is particularly necessary to form half sections of the shells with the bends 8 and 9 in order that there will be sulficient give to the shell sections 8 and 3 at he bends 8 and 9 during the welding of their adjacent edges 10 to permit a uniform and fluid tight weld to be formed along this longitudinally extending seam, the principal difficulty being not to provide a connection between the edges 10 of the half sections 3 and 3 but to form such a connection that the shell 3 provided will be fluid tight. The bends 8 and 9 permit welding of the half sections together without distorting the shell and causing it to bow from end to end.

In order tosupport the shell 3 I prefer to provide spaced legs 11 which are tied together by means of a tie-rod 12 to provide a ZL I supporting base. The legs 11 are adjustably secured to the shell 3 by means of bolts 12". The bolts 12 are passed through angle plates 13 which are riveted to the shell 3 and are screw-threaded into the legs 11 as illustrated at 14. This type of leg structure is provided in order to permit the respective chambers of the apparatus to be correctly aligned so that the extracting means of one chamber may be correctly aligned with the transfer means for transferring the cans from one chamber to the next. This type of supporting means also provides a permanent and satisfactory support for these large shell chambers while also permitting the chambers to expand at their respective ends and contract as may be required by the temperature differentiations set up within their interior.

Spirally positioned within the interior of each shell is a track 15 formed of flanged irons which are bent spirally to conform to the interior curvature of the shell 3 and er;- tend from the inlet 16 to the outlet 17 of each chamber. The runs of the spiral track 15 are spaced apart a distance substantially equal to the length of the can to be rolled through the track. The cans to be treated are caused to travel through the track thus formed by means of a reel 18 which is secured to the longitudinally extending shaft 19 of the cooker 1 and a similar reel is secured to the operating shaft 20 of the cooler 2. The reel 18 is formed of spaced wheels secured at spaced points along the shaft 19 and having flanged irons 20 secured to their periphery in position to engage the cans and move the cans through the tracks 15.

The shaft 19 of the cooker 1 is driven from any suitable source of drive mechanism as is illustrated by the worm drive 21 which is driven from the shaft 22. The shaft 22 is driven by any suitable form of prime mover operatively connected with the drive pulley or sprocket 23.

The shell 3 of the cooker 1 or cooler 2 is formed to provide inlets as follows: The shelves are provided with inlet openings such as are illustrated at the opening 16 in Figure 1 and this opening is provided with a cover plate 29 which inclines downwardly over the opening 16. Secured to the end of the plate 29 is a gate 30 which is pivoted at 31 to swmg outwardly and permit the cans to roll through the opening 16 from the chute 32. The sides of the opening 16 are normally closed by plates 33 which are secured to the plate 29 at one edge and to the shell 3 at their opposite edges so that only when the door 30 is opened there is provided means by which thesteam or other gas within the shell 3 can escape- In order prevent the cans 34 from entering the shell 3 to assume the position illustrated at 35 in Figure 2, the shell of the cooker is cut away as indicated at 36 to permit the can assuming this position to pass through the track 15 and through a similar opening 37 formed on the opposite half section 3 of the shell 3 until the same engages the edge 38 of the shell 3 at which time the can 31 which has been admitted into the shell 3 in the position 35 is ejected through a throw-out door 39 which is pivotally secured as indicated at 10 to the section ll of the shell 3.

In order to permit access to the interior of the shell 3, a cover 42 is provided for each cooker and a cover l3 for each cooler. Each of the covers 42 and 1-3 has a downwardly extending flange 14; which fits within a watersealed trough 15 which is secured to and extends completely around the upper free ends of the half sections 3 and 3 of the shell 3. The trough 45 is preferably formed by bending the edges of the shell sections 3 and 3 upon themselves in substantially U-shape as illustrated in Figure 3.

Means are provided at the inner end of the chute 32 for easing the cans into the inlets of the cooker 1, which means preferably includes a gate 82 which is pivotally supported on a crank pin 83. The crank pin 83 extends through bosses 81- formed integral with the chute 32 and the crank pin 83 is bent to form a crank Se by means of which the gate 82 is rotated to and from the position to transfer the cans through the inlets into the cooker 1. The gate 82 is provided with stops 85 which engage the under surface of the chute 32 to hold the gage 82 in proper position. A friction. lock provided by the serrated surface 86 is formed on the chute 32 to lock crank 84 in position to hold the gate 82 from oscillating as the cans travel over the same into the opening or inlet of the treating chamber.

Having fully described my invention, it is to be understood that I do not wish to be limited to the details herein set forth, but my invention is of the scope of the appended claims.
